Memorial: Would include an eight-acre plaza west of
a newly extended Greenwich Street. The plaza would have both memorials and
cultural buildings. The footprints of the former towers would be left as open
space aboveground.

Buildings: Five towers would be built, one of 79 stories,
two of 67 stories and two of 62 stories. The tallest of these would include
a skyline element, possibly an antenna or sculpture.

West Street: West Street would be covered from Battery
Park to Vesey Street, creating room for a promenade above and room to expand
memorial or cultural facilities.
